According to me,best thing ever happened to IRI is RAILCAL app -the brain child of Moderator.From a standalone, single purpose app for Seat availability,the app has steadily evolved with regular updates like offline Trip diary,Sound recording/Pic uploading etc making it the best Rail app(latest version) on Play store.
Posting comments here as there is no provision to post the same on Play store(I had already reviwed the version1)
Thanks
#moderator Sir for your innovative initiatives. All the best.
